Application filed June 7 1,

To allwhom it may concern:

Be it known that I, EDWIN F. BEUGLER, a citizen'of the-Unitedstates; residlng at Buffalo; in the county of Erie and State of New York, have invented new and useful lmpro vemen ts in Hoop -Removing Machinesyof which the followingis a specifi cation.

The object of'this invention'is to providev an improved macliine'for removing the temporary end hoops fr'o'ni the shell or body ofthe barrels after applying thepermanent' bilge hoops thereto and before applying the permanent end hoops to theisame; and

more particularly to improve'the meansfor controlling the pulling arms which engage the end hoops and remove the same from the I shell; to improve" the means for holding tlie shell against endwise motion while removing the end hoops; to'improve the means for tripping the clutch by means of the barrel when placed in its operative position in the machine for starting the hoop pullingmechanism; and to improve the'means for guiding the barrels to' and from the machine.

A machine of thesame general construetion is shownin United States Letters Pat ent No.= 1.315275, dated September. 9, 1919 and the present invention isan improve ment therein. I

'aart's" throughout the several 1923: Serial No. 6423784.

The main frame" of this machine may be variously constructed-to support the variousunovableparts, and, as shownin the drawings; preferably comprises a horizontal base orsill 1," and twostandards or posts 2,, 3; risingvfrom opposite ends of the base. The-barrelshellor body-'lffrom which the temporary end hoopst5 are, to be removed, is .moved'. by any suitable: means,' either manually or automatically,'fr,om one side of this frame. into thespacebetween the base and standards where it remai'nsfat rest until the operation of removing the temporary end h'oopshas been completed, and then the separated barrel shell and temporary hoops are discharged from the'opposite side ofthe frame preparatory toperforming other operations on the barrel for completing'it.

The barrel shell is guided into the main frame on. the receiving side thereof and discharged from its opposite delivery side. by a plurality of tracks 01' rails mounted on the base of the frame and consisting of two longitudinal horizontal receiving sections 6. 6 arranged on the front side of the frame two inclined delivery sections 7. 7y which slope rearwardly and downwardlv from'therear ends off'the horizontal sections of the rails on the rear site of the Frame. and two intermediate brackets 53* secured to the lower part of the frame and constructed of angular form'so as-to lead from the respective horizontal front rail 6 to the companion, inclined rear-raih 7 which latter is preferably formed integrally with the bracket. These receiving" track sections 6 are pivoted at their inner endsv to the rear sections 7 by horizontal bolts 6 so that the same can be either lowered into their horizontal operative position, shown by full lines in Fig. 9, orthe same can be raised into an inclined position shown by. dotted lines in the samefigure: when it is desired to makezthe'machinemore compact for trans portation. Eacli rear track. section 7 is pro.- vided at its innerend with a stop or, shoul-- der 7 for supporting the respective front: sectionG in: its horizontal position, which. latter remains in engagement therewith bygravity Endwise displacement of the barrel is prevented as the same moves forwardly over the receivingparts 6, .6 of the supporting rails this being preferably accomplished by two longitudinal guide bars: 8,8,; arranged horizontally adjacent to opposite ends of the path of the barrel, two supporting arms 9, 9, each projecting laterally from the rear end of each of the end guide bars, two brackets 10, 10, mounted on the front sides of the frame standards, and two horizontal transverse sockets 9 in which the supporting arms 9, 9 of the respective end guide bars are secured by means of set screws 11. By means of the latter the end guide bars 8, 8, may be moved toward and from each other to suit the length of the barrel from which the hoops are to be removed. Each of the sockets 9 is pivotally connected with the respective bracket 10 by a horizontal longitudinal pin 10 and normally rests by gravity against the front end of the bracket 10 which latter acts as a stop for this purpose and serves to hold the end guide bar 8 in its horizontal operative position, as indicated by full lines in Fig. 9, but permits this bar to be raised into an upwardy inclined position, as indicated by dotted lines in the same figure, when it is desired to fold the machine compactly for transportation.

The barrel which is being operated upon is held in its proper working position by inclined rear portions 7, 7, of the lower guide rails and also by two vertically swinging supporting arms 12, 12, which normally project upwardly and rearwardly across the plane of the rear portions 7, 7, of the lower guide rails and form with the latter a seat or saddle in which the barrel rests. These supporting arms are mounted at their front ends on a horizontal rock shaft 13 which is arranged transversely below the lower supporting rails and has its central part made square in cross section while its ends are round and ourna-led in suitable bearings 13 on the frame. This rock shaft is operated for raising the supporting arms 12 across the plane of the inclined rear portions 7, 7, of the lower supporting rails and holding the same at rest while the temporary hoops are being removed from the barrel, and after such removal has been completed the rock shaft 13 is turned in the opposite direction so as to lower the supporting arms 12 and permit the barrel to roll downwardly over the inclined track sections '7, 7. This is effected by a main driving shaft 1% arranged horizontally and transversely below the front sections 6, 6, of the supporting tracks and j ournaled near its opposite ends in bearings on the standards, and a cam 15 on the main driving shaft engaging with a roller 16 mounted on a cam arm 17 projecting forwardly from this rock shaft, as best shown in Figs. 1 and 11. The raising of the supporting arms 12 is effected by the high or salient face of the cam 15 and when the receding or low face of this cam is presented to the roller 16, then the supporting arms 12 drop by gravity.

A clutch mechanism is provided which antomatieally connects the driving shaft with the driving mechanism when a barrel has been fed into the operating position in the machine and permits a cycle of operations of the machine to be effected and then automatically arrests the operation of the machine. In its preferred form this clutch mechanism together with the driving mecha nism associated therewith is constructed as follows:

18 represents a main driven gear wheel which is mounted loosely upon the righthand end of the main driving shaft, 19 a primary shaft journaled in a bearing on the righthand standard of the frame and provided with a driving pulley 20 to which power is transmitted, 21 an intermediate shaft journaled in a bearing on the righthand standard and provided with a gear wheel 22 which meshes with a pinion 23 on the primary shaft and also provided with an intermediate pinion 24: which meshes with the main gear wheel 18, as best shown in Figs. 1, 2, and 8.

The coupling or clutch for connecting and disconnecting the main driving shaft and main gear wheel 18, as shown in Figs. 1, 2, 3, and t, comprises a plurality of coupling or clutch pins 25, arranged on the hub of the driving gear wheel 18, a driving or clutch arm 26 secured to the main driving shaft, a coupling dog 27 pivoted by a pin 28 to the driving arm and provided in front of its pivot with a hook 29 and in rear of its pivot with a tail 30, a spring 31 arranged in a socket 32 on the driving arm 26 and bearing against the tail of the coupling dog and tending constantly to move the latter in a direction in which its hook projects across the path of the clutch or coupling pins, and a releasing arm 33 movable into and out of the path of a nose or lug 34 on the outer side of the coupling dog and adapted to turn the latter in a direction for moving its hook out of the path of the coupling pins. The releasing arm 33 is pivotally mounted on the main frame by a pin 33", and is yieldingly turned in a direction for bringing the releasing arin into the path of the nose on the coupling dog by means of a weight 36 connected with this arm, as best shown in Figs. 1, 2, 3 and i. The outer end of the releasing arm is preferably made extensible by means of a screw 33 mounted thereon and adapted when screwed in or out on the body of the arm 33 to either lengthen or shorten the same and thus permit of setting the time at which the clutch will be uncoupled. 33 represents a trip lug connected with the releasing arm and provided with a forwardly facing trip face 33 and with an nnwardly projecting guide loop 33. 35 is a trip rock shaft which is journaled horizontally and transversely on the lower part of the main 35 which is adapted to engage with the ad? ajcent part of the mam frame, a hown in Fig. .3 to limit the foiwvard turning motion of the trip shaft. On its upper part the weight arm 35 is provided with alug 35 to which is pivoted the rear end of a trip latch 37, which latter slides onthe outer end of the trip lug 33 and is confined thereinby the loop 33 and provided on its underside with a rearwardly facing jaw 38 which is adapted to engage with the forwardly facing trip face 33 on the trip lug. 39, 39 represent two trip arm's arranged on the trip shaft and adapted to project upwardly and rearward'ly into the" path of the barrels at the operating position when no barrel is present, but which are adapted to be depressed by a barrel placed into the operative position and thereby cause the clutch to be operated so as to couple the driving gear wheel 18 with the driving shaft. As shown in Fig. 3, the-trip arm p-roj ects upwardly into the path of the barrelsat the working po sition, at which time'the releasing arm 33 is in engagement with the clutch dog and the latter is turned so that its hookis out of the path of the coupling pins of the gear wheel 18, and the latter turns idle, leaving the main drivingshaft at rest-L The trip shaft and the parts mounted thereon are yiel'dingly held in this position at this time by the weight If a barrel is introduced into the machine and occupies the working or operating position upon the seat or sad; dle formed by the inclined rear sections 7, 7, of the supporting rails and the elevated supporting arms'12,.the trip arms 39 will be depressed from the position shown by full lines in Fig. 3' to the position shown the dotted lines of the corresponding part, thereby causing the latch 37 to be pulled rearwardly and by engagement of its jaw with the trip lug turn the releasing arm 33 out of engagement from the nose of thie coupling dog in opposition to the weight 36. The instant this occurs, the spring 31 onthe driving arm causes the coupling dog to be turned in the direction for carrying its hook into the path of the coupling" pins, so that the next following coupling pin engages with this hook and thereby compels the driving shaft to turn with the constantly-turning gear wheel 18 At the beginning of this rotation of the driving shaft the frontend of the salient part or we'll portion of the cam 15 is in engagement with the roller 16 ofthe cam arm 17 and continues to remain in engagement therewith until the operation of removing the hoops from the barrel has been effected by mechanism which will be hereinafter described," and wl-r'eiii such "re mova'l hasbeen' effecterhthe lower receding faceof' this cam is presented to the roller 16 so as to permit the supporting arms 12 to drop and dischargethe stripped barrel after which the front'end of the high part of this camagain' engageswith the roller 16- and raises'the supporting arms 12 preparatory to receiving the next following barrel which is I to be stripped of its temporary hoops. The main driving shaft completes its rota"- ti'on'after the return of the supporting arms 12' to their elevated operative position, at

which time the stripped barrel also clears the trip arms 39, 39' so'that the latter are free .to be-raised into the operative position by theaction of thew'eight arm 35 and the releasing arm 33 is moved into the path of the nose or tailof the couplingdog-and the hook of the latter is moved-out of engage, ment from' the respective coupling pin- 25, whereby the rotation of the driving shaft is arrested and the gear wheel 18 continues to rotate' independently thereof. After the latch pulls the releasing arm from underneath the coupling dog 27 and the latter connects'the driving shaft 14 with the driv ing wheel 18*, the jaw of the latch slips off from the fr'ont face of the trip lug and permits the latter to be moved forwardly by the weight 36' together with the releasing arm 33 sothat this arm stands in the" path of the dog 27v ready to disengage the same from the coupling pins 25 at the end of a' cycle of operations.

In the absence of any provision to prevent it, the trip arms 39, 39 are liable to remain in their upwardly projecting position and interfere with the free discharge of the barrel notwithstanding that the clutch has been tripped and the supporting: arms 12" have. been depressed. To prevent the barrels from getting stuck at this time, means are provided for positively depressing the trip arms out of the path of the'barr'elswlienever the latter are to bedis'charged' from the machine. This is accomplished by providing each trip arm with a roller 39 which is arranged in the path of'one of the supporting arms and adapted to be engaged by the latter when the same is depressed and thus positively move the trip arms out of the path of the barrel, as shown in Fig. 4, and insure discharge of the barrel from the machine.

In order to insure a complete rotation of the main driving shaft and cause the same to be arrested at a definite point after each cycle of operations, a centering device provided which comprises a centering wheel 40 secured to the left hand end of the driving shaft 14 and provided in its periphery with a curved centeringreccss or notch 41, a centering lever 42 pivoted on the adjacent standard of the frame and provided on one of its" arms with a centering roller 43 maps.-

ed to engage with the periphery and the notch of said centering roller, and a spring 44L connecting the other arm of the centering lever with the main frame.

After a barrel has been placed in the working or operating position of the machine, and the trip arms 39, 89 have been depressed so as to couple the driving shaft with the source of power, the means which hold the barrel in its operating position and strip the temporary end hoops therefrom come into action. These holding means comprise twovertically movable holding or retaining jaws 15 which are adapted to engage the upper surface of the barrel shell lengthwise on opposite sides of its bilge, each of these aws being preferably arranged to engage with one or" the permanent bilge hoops 46 and also with the shell on opposite sides of this permanent bilge hoop. These two holding jaws are mounted on a verticallyswinging yoke: which comprises two rock arms &7 pivoted by means of horizontal transverse pins 48 on the upper parts of the standards, and a cross bar 49 connecting the rear ends of these; rock arms and carrying the jaws l5. Each. of the holding jaws is constructed in accordance with my invention and comprises a hollow guide head 50 which is secured to the rear side of the cross bar of the yoke by means of bolts 51 passing through the front wall of this head and a horizontal slot 49 in this cross bar, and a plurality of upright holding teeth or keepers 52 arranged side by side in a transverse horizontal row and adapted to engage their lower ends with the periphery of the barrel body and the respective bilge hoop 46 thereon, and a retaining rod 50 extending horizontally through. vertical slots 42 in the holding teeth and supported at its ends on the end walls of the guide head. While the barrel is being moved to and from the position in which thesame is operated upon the yoke is elevated so as to rais the holding or retaining jaws wnereby the teeth thereof slide downwardly by gravity until the upper ends of the slots thereinengage with the retaining rods 50. After the barrel is in the position to be operated upon the yoke is lowered so that one or more of the intermediate keepers or teeth of each retaining jaw are caused to rest with their lower ends by gravity on the periphery of one of the permanent bilge hoops 46 .and those keepers or teeth of each jaw at the ends of the row are caused to engage with the periphery of the barrel body on opposite sides of the respective bilge hoop, whereby the barrel is not only held down, but also prevented from moving endwise inasmuch as the weight of the keepers holds the barrel down and some of the keepers of both jaws engage with the side edges of both bilge hoops and thereby prevent movement thereof in. direction lengthwise of the axis of the barrel. Eachset of retaining teeth are mounted loosely in the head of the respective jaw so that they are free to adapt themselves to a bilge hoop and barrel body and engage the respective hoop at its periphery and also at its edges, and still permit of a variation in the location of this hoop on the barrel body within certain limits. Those teeth which engage with the periphery of the barrel are only pushedup slightly in the guide head upon engaging the body while those engaging the periphery of the bilge hoop are pushed up in the head a greater extent, as shown in F 7. As to which of the teeth engage with the hoop and which with the barrel body depends on the location of the hoop and retaining jaw relatively to each other. By adjusting the holding jaws lengthwise on the cross bar of the yoke through the medium of the adjusting bolts 51 and slots 49, it is possible to shift the retaining jaws to approximate the location of the bilge hoops on bodies of different dimensions.

The means provided for rocking the yoke so as to move its holding or retaining jaws into and out of their operative position, comprise a forward extension 54 arranged on one of the rock arms 47 so that the same in effect forms a double-armed lever, a lower cam lever 55 pivoted to swing vertically on the lower part of the adjacent standard and provided on one of its arms with a roller 56 while its other arm is connected by means of an upright rod 57 with the lever 54, a rotary cam 58 mounted on the main shaft 14 and engaging with the roller 56, and a spring 59 connecting the cam lever 55 with an adjacent part of the main frame. The yoke is capable of being adjusted bodily in a vertical direction on the end frame, and the connection between its cam lever and the shifting rod 57 is also made adjustable, so as to permit of adapting the machine to strip the temporary end hoops from barrels which vary in diameter. The adjustment of the yoke on the frame is effected by shifting the pivot pins 48 of the yoke into one or another pair of corresponding openings 60 formed in two upright rows on the upper parts of the standards and providing these pins with handles for manipulating the same. The adjustment between the yokelever 54 and the shifting rod 57 is effected by an upright adjusting sleeve 62 which receives the externally sorewthreaded upper end of this adjusting rod, screw nuts 63, 64 applied to this red above and below this adjusting sleeve and a horizontal transverse pivot pin 65 connecting the adjusting sleeve 62 with the yokelever 54.

After the clamping jaws 4-5 have been lowered into engagement with the upper side of the barrel, the means which strip or remove the temporary hoops from the ends of the barrel perform their function, the same being constructed as follows:

66 represents two pulling leverseach of which is of elbow-shape and pivoted by means of a pin 67 on the rear side of one of the standards, so as to swing in a vertical plane and has one of its arms68 projecting upwardly while its other or lower arm 69 projects laterally. 70 represents two pulling cams arranged on opposite ends of the main driving shaft 14 adjacent to the outer side of the standards. 71 represents two intermediate cam levers each of-which is pivoted by means of a horizontal transverse pin 72 to the outer side of one of the standards so as to swing in a vertical plane and provided on its front arm with a' roller 73 which engages with the respective pulling cam 70 while its rear arm is provided with a socket 71 which contains a bearing block 71" engaging with the upper side of the lower arm of the respective elbow pull lever 66, said blockbeing adjusted in said socket by an adjusting screw 71 and held in place after adj ustment by a set screw 71 Means are provided for keeping the lower arm of each pulling lever yieldingly in engagement with the respective cam lever 71, which means preferably consist of a spiral spring 66 arranged within a cavity 66 in a cap 66 opposite the hub 66- of the respective pulling lever which cap isconnecte'd at its outer end with the pivot pin 67 V by a cotter pin 67 The spring 66 is connected at one end with the outer end of the cap 66 while its inner end is connected with the hub of the pulling lever 68, 69, as shown in Fig. 10.

The pivot pin 67 is preferably provided with a surrounding sleeve67 which prevents the coils of the spring 66 surrounding the same from gripping the pivot pin arid interfering with the free turning of the pulling lever on this pin.

74, Tel represent two pull bars or rods which are arranged transversely in rear of the upper parts of the standards with their opposing inner ends overhanging the opposite ends of the place where thebarrels come to rest to be operated upon. Each of these pull bars is pivoted at its outer end to the upper arm 68 of one of the pulling levers by means of a horizontal longitudinalpin 7 5, so that this bar can swing in a vertical plane. On the underside of its inner part, each of the pull bars is provided with a claw or hook 78 which is adaptedto engage with the inner edge of the upper part of therespective hoop intended to be removed from the barrel body. The inner ends of the pulling bars are raised and lowered for the purpose of en gaging and disengagingthe claws 78 with the temporary end hoops which means are 7 preferably so organized that they operate in unison with the retaining aws 45 and con- ,sist of two shifting arms '79 mounted on the cross bar 49 of the yoke and each provided at its rear end with a shifting roller '79 which engages with the longitudinal channel of the guide bar 80 which ismounted on 'the inner part of the respective pulling bar and which is preferably U-shaped in cross section. For the purpose of enabling the vertical movement of the pulling bars to be adjusted to secure the right throw for a given barrel each shifting arm is mounted on the yoke'cross bar so as to be adjustable thereon, both vertically and horizontally and each guide channel bar 80 is mounted on its respective pulling bar so as to beicapable of vertical adjustment thereon. For this purpose each of the shifting arms is provided at its rear end with two uprightslots 81, which receive bolts 81, also passing through the slot 19 for securing the shifting arm to the rear side of the yoke cross bar. To prevent the shifting arms from slipping horizontally on the yoke cross bar, these parts are provided on their cooperating surfaces with interlocking ribs or serrations 82, 82" extending vertically on these parts, as shown in Figs. 1, 2, 5 and 7. Each of the guide bars 80 may also be adjusted vertically or tilted at the desired angle on its pulling lever by means of bolts 80 passing through the pull- 'most position and the pulling bars are raised into theirhighest position by means of the springs 66*, so that the claws of the pulling bars andthe holding jaws of the yoke are elevated out of the path of the barrel. If'now, a barrel'is placed in the working position and the machine begins a cycle of operations by reason of the depression of the trip arms 39, 39 by the barrel, the loweringof the yoke for engaging theholding aws with the upper side of the barrel also'causes the pulling bars to be lowered by the shifting arms 79and guide bars 80, so that in the lowered posi- "tion of these pulling bars their claws engage with or are arranged close to the upper side of the barrel adjacent tothe inneredges of the temporary end hoops. Immediately after the pulling bars have been thus lowered, the high parts of the pulling cams 7 0 engage with the rollers of the cam levers 71 and turn the latter from the position indicated by full lines in Fig. 10 to the position shown by dotted lines in the same figure, whereby each of the pulling levers and its companionpulling bar and associated claw are moved from their innermost poition to their outermost positions indicated by dotted lines in Fig. 2. During this movement the two claws of the pulling bars engage with the inner edges of the temporary end hoops on the barrel on the top of the latter and forcibly strip or remove the same from the barrel lengthwise of the axis of the latter, as indicated by dotted lines in the last-mentioned figure. After this occurs, the low parts of the pnlling cams are again presented to the cam levers 71 and the high part of the cam is presented to the lever 55, thereby caus ing the yoke to be elevated, the pulling levers to be turned so that their upper arms swing inwardly and the pulling bars to be elevated so that the pulling mechanism again clears the path of the barrel. In order to permit of adjusting each pulling bar on the respective pulling lever to suit barrels of different diameters, the upper arm of this lever is provided with a row of openings 83 into one or the other of which the pivot pin of the pulling bar may be placed to suit the diameter of the barrel which is being operated upon. The position of the claw of each pulling bar may be adjusted parallel with the axis of barrel so that this claw may be adapted for pulling off the hoops from barrels which vary in length by means of a longitudinal row of openings 75 any one of which may be engaged by the pivot pin 75.

Immediately after the pulling operation has been completed and the holding jaws and pulling claws have resumed their normal inoperative position, the machine completes its cycle of operations during which the supporting arms 12 are permitted to drop for discharging the barrel rearwardly and these supporting arms are then again raised into their elevated position preparatory to receiving the next barrel which is to be stripped.

While the barrel is being discharged from the rear side of the machine by rolling down the rear inclined track sections 7, '7, the detached temporary end hoops 5 also roll rearwardly and are guided at this time by rearwardly and downwardly inclined channels 7, 7 mounted on the adjacent base portion of the main frame, and are then taken care of by the attendants. In order to prevent these removed temporary end hoops from interfering with the working parts of the machine and also causing them to be directed rearwardly from the machine, two rear side guide bars 85 are provided which support the upper parts of the removed temporary end hoops and direct them rearwardly from the machine. These side guide bars are mounted on the upper parts of upright rods or posts 85 secured at their lower ends to the delivery channels 7, 7.

These guide bars are capable of vertical adjustment on the posts 85 by means of sleeves 85, which are secured to the bars 85 and in which the posts are secured by set screws 85, as shown in Figs. 1, 2 and 6.
